I am looking at nursing covers that will be comfortable to use during the summer months (baby is due in March). I like the prints and size of the Bebe Au Lait covers, but haven't been able to check out the fabric. How lightweight are the Bebe Au Lait covers? Are they comfortable? Or do you feel like they get too hot?

I found out this week that they make a muslin verison of their cover. I'm wondering if that fabric would be better or more comfortable in the summer. Does anyone have any experience with the muslin covers? It seems like they are relatively new.
